It’s not unusual to hear crypto referred to as “The Wild West.” That’s because it kind of is. A lack of regulation is somewhat the point of cryptocurrency, but this leaves room for vulnerabilities. Enter cryptocurrency security companies. Crypto security companies provide software tools to detecthacks, trade funds safely, and audit existing code to prevent vulnerabilities. However, there aresmart contract audit servicesthat can be conducted separately.
If you’re a biz working with blockchains, you’re going to want to ensure the code is solid, and you may also want enterprise-grade software to store your crypto. Below we take a look at a few crypto security companies and explore what roles they play in keeping crypto funds safe.

Why Do We Need Crypto Security Companies?
Just like you need good physical security to guard a bank safe, or good security cameras to guard the cash under your mattress, good crypto security is important in protecting your funds.
While cash can only ever be physically stolen, there are many ways your digital funds can be compromised:
- Smart contract hacks and exploits
- Phishing attacks and password scams
- Wallet hacks and credential leaks
- Government seizure of funds traced back to illicit wallet addresses
- Lost funds while transferring from one exchange to another
To Sum It Up
Any time you’re dealing with large sums of money, it’s important to have dependable security. Everyday traders and non-technical business owners may not even know all of the different ways their funds can be stolen. This is why it’s important to use security solutions like the ones outlined above for effective protection.
